Steel Pipe Specifications Under British Standard

I. Overview of steel pipe specifications under British Standard

The steel pipe specifications under the British Standard are mainly divided into two categories, one is formulated according to the metric system specifications, and the other is formulated according to the imperial system specifications. In the steel pipe specifications formulated according to the metric system specifications, the diameter unit is millimeters and the wall thickness unit is millimeters or inches; in the steel pipe specifications formulated according to the imperial system specifications, the diameter unit is inches and the wall thickness unit is SWG or BWG. In addition, there are some special steel pipe specifications, such as seamless steel pipe for structural use and boiler use, etc., which are different according to different applications as well as different manufacturing processes.

II. Common steel pipe specifications under British Standard

1. BS EN 10255 steel pipe

BS EN 10255 steel pipe is a welded steel pipe for low-pressure fluid transportation. It is formulated according to metric specifications, with diameters from 15mm to 165mm and wall thicknesses from 1.8mm to 6.35mm.

2. BS1387 steel pipe

BS1387 steel pipe is a commonly used plain welded steel pipe for gas, water supply and drainage. It is formulated according to metric specifications with diameters from 15mm to 150mm and wall thicknesses from 1.6mm to 5.4mm.

3. BS EN 10219 steel pipes

BS EN 10219 steel pipe is a welded structural steel pipe for use in the construction and mechanical fields. It is formulated according to metric specifications with diameters from 21.3mm to 219.1mm and wall thicknesses from 1.5mm to 8.0mm.

4. BS EN 10210 Steel Pipe
